AudioRealism is a Swedish software company that develops virtual instruments focused on recreating the sound and workflow of classic electronic music hardware. The company is best known for its Bass Line series (ABL, ABL2, ABL3), a line of plugins that emulate the Roland TB-303 using analog-modeling DSP, a built-in step sequencer patterned after the original hardware, and a Wave Analyzer that can transcribe audio of a real TB-303 into an ABL3 pattern.

Beyond the 303 emulations, AudioRealism's catalog includes the AudioRealism Drum Machine (ADM), which models vintage Roland-style drum machines, the ReDominator polyphonic synthesizer, and Semi Modular X (ASM1X), a semi-modular analog-style synth. The company also produces sample packs such as a TR-909 library and distributes several of its instruments as Rack Extensions for Propellerhead/Reason in addition to standard VST, VST3, AU, and standalone formats.

AudioRealism's tools have a following in acid, techno, house, and rave production circles, where the authenticity of its 303 emulation has given ABL3 a reputation as one of the better-regarded software alternatives to the original hardware.

AudioRealism has 5 products cataloged on Equipboard, including Synth Plugins and Drum Machine. Their gear is featured by 9 artists, with the strongest followings in Electronic, Pop, and Jazz. Notable users include Deadmau5, Plaid, and Plastikman.
